A tutorial worth gold. You will learn how to build a full ERC-20 lottery game, Including Frontend, Backend and smart contract!
A lottery game that pays prizes with your own ERC-20 token. Users will choose 6 numbers and at every draw interval winning numbers will be obtained and a jackpot offered for anyone that matches the right numbers.
